Subject: arm64: dts: imx8mm-var-som: Add 32.768 kHz clock to PMIC
X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=e3e61bce5f0851592a1ac62efdac78b5aaa4c09c;p=linux.git

arm64: dts: imx8mm-var-som: Add 32.768 kHz clock to PMIC

The ROHM BD71847 PMIC has a 32.768 kHz clock.  Adding necessary parent
allows to probe the bd718x7 clock driver fixing boot errors:

    bd718xx-clk bd71847-clk.1.auto: No parent clk found
    bd718xx-clk: probe of bd71847-clk.1.auto failed with error -22
